摘要：
The design of an acoustic filter utilizing low frequency acoustic vibrations (infrasound) for coal mine water treatment is described. Pistons causing acoustic vibrations are built into the end faces of the filter. They are rigidly interconnected and suspended on flexible membranes. The filter casing is divided by a filter partition into the filtrate and initial product sections.
